 Abstract – Many design courses require students to maintain a paper-based personal design notebook or journal. The potential advantages of a digital notebook have been described in the literature, but few reports can be found on the use of digital notebooks in practice. This paper describes the design and implementation of a cloud-based collaborative workspace to provide a shared team design notebook. The shared workspace uses Microsoft SharePoint sites and Microsoft OneNote notebooks as the main components. SharePoint sites were created for 34 design teams in a 2nd-year engineering design course. Each site had a team notebook, document library, discussion forum, and task scheduler. Instructions and training were provided at the beginning of the course. Students were able to use the tools with little difficulty, and were able to use them as an effective replacement for a paper notebook. However, many teams did not make full use of the available capabilities, and there was little evidence of higher-level collaborative activities. The described implementation is technically and financially feasible, is scalable to large classes, and satisfies most of the requirements of a collaborative design notebook. However, scaffolding and training are needed to ensure that students collaborate effectively.

Objective The present study investigated whether and how different human–robot interactions in a physically shared workspace influenced human stimulus–response (SR) relationships. Background Human work is increasingly performed in interaction with advanced robots. Since human–robot interaction often takes place in physical proximity, it is crucial to investigate the effects of the robot on human cognition. Method In two experiments, we compared conditions in which humans interacted with a robot that they either remotely controlled or monitored under otherwise comparable conditions in the same shared workspace. The cognitive extent to which the participants took the robot’s perspective served as a dependent variable and was evaluated with a SR compatibility task. Results The results showed pronounced compatibility effects from the robot’s perspective when participants had to take the perspective of the robot during the task, but significantly reduced compatibility effects when human and robot did not interact. In both experiments, compatibility effects from the robot’s perspective resulted in statistically significant differences in response times and in error rates between compatible and incompatible conditions. Conclusion We concluded that SR relationships from the perspective of the robot need to be considered when designing shared workspaces that require users to take the perspective of the robot. Application The results indicate changed compatibility relationships when users share their workplace with an interacting robot and therefore have to take its perspective from time to time. The perspective-dependent processing times are expected to be accompanied by corresponding error rates, which might affect—for instance—safety and efficiency in a production process.
